Step 1

First pat dry the fish fillets with a paper towel or clean cloth to remove excess moisture. Then cut them into small cubes and season them with salt and white pepper to enhance the flavour.

Step 2

In a bowl, add plain flour, cornstarch, garlic powder, and baking powder and mix everything well. Follow with the egg white and gradually pour the water in. Combine well until it forms a smooth batter.

Step 3

Add the fish cubes to the batter and make sure to coat each piece with batter. Fry the battered fish in the preheated hot oil for 3-4 minutes or until both sides are crispy golden brown. Then remove the fish from the oil and place them over the cooling rack or paper towel.

Step 4

Combine sauce ingredients ( vinegar, tomato ketchup, sugar, salt, cornstarch, water, and chicken powder ) in a small bowl and mix everything well. Set it aside.

Step 5

Heat the large wok/pan over medium heat, drizzle oil and stir-fry the garlic onion and bell peppers.

Step 6

Pour the sauce in and cook until the sauce starts to get thickened and glossy. Then add the fried fish pieces and toss everything well with the sauce.
